I was kinda predicting in my head that the last chapter would be a their wedding, and I feel like this super confirms it!
I love Nobara just going full steam ahead. She doesn't think to deeply on "how would other people see this" so she doesn't get embarrassed by much and that allows her to focus on attaining what she wants. If Yukino was the one that was going to drive forward things like the wedding, there would be lots of pauses as she tries to stop blushing at every step. That would be cute and would give us material for a lot more chapters but seeing Nobara's drive shows just how loved Yukino is.
